摘　　要：在尾焰模拟器中,需要用加热棒的辐射模拟尾焰辐射。为了达到足够的辐射强度,需要将加热棒加热到极高的温度。这时,电场、磁场、温度场等多物理场共同作用于最终结果。对于多物理场耦合的系统进行建模求解传递函数非常困难繁琐,为了对系统进行更精确的控制,利用有限元法对系统模型特性分析,通过系统辨识求出传递函数;并利用补偿法构建解耦补偿器对耦合系统进行解耦控制,通过Simulink搭建系统框图并进行仿真实验证明解耦后的系统具有更好的控制效果。In the tail flame simulator,it is necessary to simulate the tail flame radiation with the radiation of the heating rod.In order to achieve sufficient radiation intensity,the heating rod needs to be heated to an extremely high temperature.At the same time,multiple physical fields such as an electric field,a magnetic field,and a temperature field act together on the final result.It is very difficult and cumbersome to model and transfer the transfer function for multi-physics coupled systems.In order to control the system more accurately,in this paper,the finite element method is used to analyze the characteristics of the system model;and the transfer function was found through system identification.The decoupling compensator performs decoupling control on the coupled system.The system block diagram is built by Simulink and simulation experiments show that the decoupled system has better control effect.
